    Description

    The threat of emerald ash borer (Agrilus planipennis) has necessitated ash seed collection to preserve the ash genetic resource. For ash species found only in natural areas, we have developed seed collection methods that require no special training or certification. Collection techniques for natural areas include pole pruners for branches lower than 30 ft (9 m) and ropes or rope saws for higher branches. Seed collection must be timed correctly by examining samara color, seed coat color, and embryo size to be sure that seeds are fully mature. Documentation of seed identity and post-harvest handling of seeds are discussed.
